In the preferred embodiment of the present invention, the stop ring 3 and the main body 1 are formed integrally. The stop ring 3 protrudes outward from a periphery of the main body 1.

In operation, referring to FIGS. 5-8 with reference to FIGS. 1-4, the connecting member 2 is mounted on the main body 1, and the fitting section 11 of the main body 1 is connected with a mechanic device, such as an electric tool or a pneumatic tool. When the mechanic device is rotated, the main body 1 is driven to rotate the connecting member 2 which rotates the operation member 4, so that the operation member 4 is driven to achieve cleaning and grinding functions. In such a manner, the connecting member 2 is connected with the main body 1 to achieve the cleaning and grinding functions. Besides, the connecting member 2 is removed from the main body 1 to replace the operation member 4. At this time, the connecting member 2 is combined with the operation member 4, so that the connecting member 2 and the operation member 4 are replaced simultaneously. In such a manner, the operation member 4 includes a steel brush, a nylon brush, a bristle brush, a steel wool, a grinder, a cloth wheel, a wool wheel or a sponge, so as to provide different cleaning and grinding functions, including rust cleaning (or derusting), waxing, brushing, polishing or the like.

In addition, the fitting section 11 of the main body 1 has a rectangular shape, a polygonal shape or an irregular shape to correspond to mechanic devices with different shapes and sizes. Further, the fitting opening 111 of the main body 1 cooperates with the coupling member 5 whose coupling portion 51 is used for coupling different types of mechanic devices. For example, when the coupling portion 51 of the coupling member 5 is a post, the coupling portion 51 of the coupling member 5 is inserted into a pneumatic drill. Alternatively, when the coupling portion 51 of the coupling member 5 is a socket, the coupling portion 51 of the coupling member 5 is mounted on a smaller mechanic device that cannot be mounted directly. Further, the at least one mounting cavity 141 of the main body 1 is used for receiving the stop ring 3 when the connecting member 2 is detached. Further, the at least one locking hook 212 of the connecting member 2 is hooked on the stop ring 3, so that the connecting member 2 is locked onto and positioned on the main body 1. Further, the passage 41 of the operation member 4 allows proceeding of cleaning and grinding actions.

When in use, the main body 1 is directly connected with the mechanic device or combined with the coupling member 5 to connect the mechanic device according to the types of the mechanic device, so that the main body 1 and the coupling member 5 are available for mechanic devices of different types. In addition, the connecting member 2 is combined with the operation member 4 of different types so as to achieve different cleaning and grinding functions, including derusting, polishing, grinding and cleaning. Thus, the main body 1 is selectively connected with the connecting member 2 which is combined with the operation member 4 of different types

In practice, when the cleaning grinding head structure is used for derust a metallic workpiece, the operation member 4 is in the form of a steel brush, a steel wool or a grinder, to remove the rust on and grind the metallic workpiece. Then, the at least one locking hook 212 of the connecting member 2 is detached from the stop ring 3 to unlock the connecting member 2, so that the connecting member 2 is detached from the connecting section 12 of the main body 1. Then, the connecting member 2 is replaced a new connecting member 2 which is combined with the operation member 4 which is in the form of a cloth wheel or a wool wheel. At this time, a paint is applied on the operation member 4. Then, the new connecting member 2 is mounted on the main body 1, and the operation member 4 is used for polishing the metallic workpiece.

Alternatively, when the cleaning grinding head structure is used for cleaning a bolt, especially the bolt on a car, the passage 41 of the operation member 4 is mounted on the bolt. In such a manner, when the operation member 4 is rotated, the bolt is rubbed and cleaned by the inner face of the passage 41, so that the operation member 4 cleans the bolt easily and efficiently.

Accordingly, the ribs 2111 of the connecting member 2 are inserted into and secured in the slots 131 of the main body 1, and the at least one locking hook 212 of the connecting member 2 is hooked on the stop ring 3 which is locked in the locking groove 14 of the main body 1, so that the connecting member 2 is locked onto and positioned on the main body 1 steadily. In addition, the ribs 2111 of the connecting member 2 engage the slots 131 of the main body 1, so that the connecting member 2 will not slide during rotation, thereby preventing the connecting member 2 from being loosened and detached from the main body 1 during the rotation at a high speed.
